1, no, wireless charging will not reduce the performance of the battery faster. Battery manufacturers design the amount of energy stored in batteries to determine the amount of electricity we can use. The manufacturer sets a fixed upper cut-off voltage and a lower cut-off voltage, and electrically cycles between the two voltage ranges, so long as we choose the right voltage range, we can cycle the battery thousands of times.
2, long-term use of radio charging will not affect the mobile phone. Wireless charging is characterized by no charging line restrictions, affected by nickel-metal hydride batteries, this battery has memory, the best way to use isAfter use, the battery can be charged to achieve the best state. The wireless charging method does not have the bondage of the line, and takes it with each charge, reducing the complexity of plugging and unplugging the data cable.
3, wireless charging is usually not harmful to mobile phone batteries. Wireless charging converts electrical energy into special energy through electromagnetic induction and transfers it between magnetic fields to achieve charging of mobile phone batteries. This charging method does not require the use of data cables, making charging more convenient and safe. Under normal circumstances, wireless charging operates at a frequency below 1MHz and will not affect the phone's communication signal.
4, "long-termUsing a wireless charger has no effect on your phone's battery. Wireless charging is the use of electromagnetic induction principle, through the coil coupling to achieve the transfer of energy. Wireless charging technology of mobile phone is a kind of circuit which is converted into charging circuit through transmitting circuit through power management module.
5. There is no harm in this case. Wireless charging technology transmits electricity through electromagnetic induction, and the transmission method is different from that of wired charging. Under normal conditions of use, the wireless charger can provide electricity stably without adverse effects on the battery. In order to ensure the health of the battery, it is necessary to pay attention to the quality of the charger and the use environment, and avoid a long timeThe high temperature environment can protect the mobile phone battery to the greatest extent.
6, no harm to mobile phones. Wireless charger uses the latest wireless charging technology, by using the alternating magnetic field generated between the coils, the transmission of electrical energy, inductive coupling technology will become a bridge connecting the charging base station and equipment.
Wireless charging base input 5W, through the base to the Apple built-in reception will get more than 5WIt should be slightly faster than the 5W of wired charging, or quite similar. Is the power wireless transmission of low efficiency, waste, heat. It is better to plug the 5W line into the wireless charger base directly into the mobile phone, 5W wired charging, must be much faster than wireless.
The first: use Apple 29W USB PD fast charger, this method can help iPhone X to reach enough power in a short time. The second: use Apple 5V/4A charger to charge, this method is the most cost-effective way to charge. Third: Use Apple's standard 5W charger to charge, this wayThe power is low, the phone is hot but the charging time is longer.
Apple cable charge well. The advantage of the magnetic magnet is that it can be adsorbated near, and the adsorption can be charged.
